Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr
Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.
Turbidity model input and output data and associated imagery from May 2022 to November 2023 at Colorado River near Cameo, Colorado Turbidity model input and output data and associated imagery from May 2022 to November 2023 at Colorado River near Cameo, Colorado
Regression models were developed with reflectance values from remote-sensing imagery and concurrent turbidity measurements during a 2 year period at Colorado River near Cameo, Colorado streamgage (U.S. Geological Survey station number 09095500). Three types of remote sensing systems were tested including satellite- and ground-based sensors. Models relate the explanatory variables...
Radiocarbon ages from sites in Peru generated during joint volcano hazards projects carried out by the U.S. Geological Survey Volcano Disaster Assistance Program, Instituto Geofisico del Peru, and Instituto Geologico, Minero y Metalurgico del Peru Radiocarbon ages from sites in Peru generated during joint volcano hazards projects carried out by the U.S. Geological Survey Volcano Disaster Assistance Program, Instituto Geofisico del Peru, and Instituto Geologico, Minero y Metalurgico del Peru
We present the results of 14C age analysis of samples collected during multiple projects that are part of an ongoing, joint initiative of the U.S. Geological Survey Volcano Disaster Assistance Program with the Instituto Geológico Minero y Metalúrgico and Instituto Geofísico del Perú. These projects are part of a wider effort to better understand Peru’s many volcanoes and provide baseline...
Basin characteristics rasters in support of estimation of magnitude and frequency of floods for rural, unregulated streams in Virginia and West Virginia, 2025 Basin characteristics rasters in support of estimation of magnitude and frequency of floods for rural, unregulated streams in Virginia and West Virginia, 2025
This dataset was produced by the US Geological Survey (USGS) as a supporting dataset for calculating stream-gage basin characteristics within the Virginia and West Virginia StreamStats applications. This data release contains the supporting raster representations of various soil and land use attributes generated as explanatory variables for the 2025 flood-frequency study for Virginia and...
Rapid Geomorphic Assessment of Little Flatrock Creek Stream Network, Ohio, 2019 Rapid Geomorphic Assessment of Little Flatrock Creek Stream Network, Ohio, 2019
The Maumee River network contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved P, to the Western Lake Erie Basin. Most Maumee River headwater streams are agricultural, with conservation management focused on limiting sediment and nutrient transport from cropland to the stream network. However, several studies have shown streambank...
Chemical and physical data for sediment source tracking in Little Flatrock Creek, Ohio - streambed sediment, 2019 Chemical and physical data for sediment source tracking in Little Flatrock Creek, Ohio - streambed sediment, 2019
This data release includes physical and chemical data for streambed-sediment samples collected at 7 locations in the Little Flatrock Creek basin in Paulding County, Ohio during July 2019. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 41 metals, and particle-size analysis; not all samples had enough for all analyses. Source samples were...
Fallout-radionuclide activity in samples collected from fine-grained, streambed sediment in the Little Flatrock Creek stream-channel network, Ohio, 2019 Fallout-radionuclide activity in samples collected from fine-grained, streambed sediment in the Little Flatrock Creek stream-channel network, Ohio, 2019
These data are comprised of beryllium-7 (7Be) and excess lead-210 (210Pbxs) activity for fine-grained, mobile, streambed sediment at seven reaches in the Little Flatrock Creek stream-channel network. This basin is monitored in cooperation with the Ohio Department of Natural Resources. During the period July 26-27, 2019 (summer low flow), the thickness and spatial extent of soft, mobile...
Particle-size distributions for streambed sediment in two Maumee River tributaries, July 2019 Particle-size distributions for streambed sediment in two Maumee River tributaries, July 2019

Chemical and physical data for sediment source tracking in Little Flatrock Creek, Ohio - source samples, 2021 Chemical and physical data for sediment source tracking in Little Flatrock Creek, Ohio - source samples, 2021
Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed sediment from Little Flatrock Creek, Paulding County, Ohio. These data will be used in a sediment-source mixing model to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were identified as one of four land-cover...
Chemical and physical data for fingerprinting 2022 sediment in East River, Wisconsin, tributary to the Fox River, Green Bay, and Lake Michigan - suspended sediment collected with autosampler Chemical and physical data for fingerprinting 2022 sediment in East River, Wisconsin, tributary to the Fox River, Green Bay, and Lake Michigan - suspended sediment collected with autosampler
Data include total nitrogen and organic carbon, total metal, and particle-size analyses of upland (cropland, woodland, gullies, roads) and streambank from the East River basin, Brown County, Wisconsin that was collected in July and August 2022. These data will be used in a sediment-source apportionment tool to attribute the proportional contribution of individual sources to suspended...

Measurements of velocity and bathymetry in the tailwater of Barkley Dam (Cumberland River) near Grand Rivers, Kentucky, November 9–10, 2021 Measurements of velocity and bathymetry in the tailwater of Barkley Dam (Cumberland River) near Grand Rivers, Kentucky, November 9–10, 2021
These data are bathymetry (river bottom elevation) and depth-averaged velocities generated from the November 9–10, 2021, survey of the Barkley Dam tailwater from just downstream from Barkley Dam to approximately 600 feet upstream from the US 62 bridge (about 0.8 mile total length). Bathymetry and velocity data were collected using an acoustic Doppler current profiler (ADCP) with an...
